I got a quad wrapped corbin blade, rebel star white led and the set of colored discs (along with many other parts) to convert my ROTJ Luke Force FX saber. My blade only lights up well about half of the length with the entire top half leaving a lot to be desired and no matter what disc I use the blade is always white. I doubled some similar colors up and got just barely some color but still basically white. Am I doing something wrong? They are a far cry from the examples on the colored disc pic in the store.

Thanks!
